Mini Pop Wings

Mini Pop Wings, a Slow One and a Reasonably Fast One

There seems to be an upsurge in these little 24” EPP wings at the flying fields, at least I see many these days, so I had to have one or two, maybe three.   We fly them at my work out back in San Jose.  They are distributed  and made by Tech One Hobby. 

They are a lot of fun, fly very slow, so slow you can do combat with little to no damage.  There are a lot of videos of people catching them on landing as well as other tricks.  All weigh less than half a pound AUW. 

Nitroplanes sells the bare wing for $25 or an ARF version for about $60 that includes the motor, esc, servos.  For the ARF, just add batts and rx and you’re ready to go pretty quick. 

I’ve been using the little orange Hobby King receivers for $10 and remove the case to make it fit better, see pics. 

The slow version

Here is a pic of mine, several graphic designs are available and they seem to add new ones consistently.  5x3 GWS prop, ~5-8A ESC.

The ARF version link is listed below.

The center foam cavity has the HK RX on the left and the ESC on the right.  Battery is up front and you can see the carbon I added for reinforcing the battery cavity which tends to be a weak spot. 

This one flies on 2S500 batts although you can go up to 800 if you like.  With the 500 batts you need about 10 grams of weight in the nose, but with the 800s you can get by without additional nose weight.

I use the 500maHr batts myself, and made up the needed nose weight with some carbon reinforcement and some finishing nails in the leading edge for added combat durability.

There is a nice foam block on the front to act as a skid and the battery mounts just behind this. 

The T 1306 motors provided in the ARF are discontinued so, after the motor mount broke, I bought this one as a replacement after my motor mount broke. 3200kv, HK1612

The fast version

We had been flying the slow ones for a while, then someone spotted this guy, JohnnyMeg on rcgroups under the heading of “insanely fast mini pop wing”.  Seemed very fast on the vid and noone was disappointed.

JohnnyMeg was strengthening them with some nylon tape on the nose, beefed up the motor, esc and servos and sold them for ~$100.  So, several of us bought them.  3S850 batts and 5x4.3 GWS prop. 

Mine measured 22A, on 3S, so about 440w and it weighs 8oz.  400w/lb!  WOW!  So, we call this the Mega mini pop wing, of just the Mega Poppy for short.  The name has nothing to do with the size and everything to do with the power system. 

Below are both of them in the same pic.

I had some trouble with the ESC as it caused erratic motor operation, seemed to lose timing setting.  The ESC that JohnnyMeg used didn’t have the ability to change timing setting, so I substituted a more upscale one where I could set timing.  Worked well.  The motor RPM tached at about 24000 RPM on 3S850. 

He was secretive on the parts he was using.  So, of course, I took it as a personal challenge to figure out what he was installing.  Below is the part list of what I’m using along with HK links.


Motor, 24 gr Hextronic, 3000kv

Prop, GWS 5x4.3

Battery, 3S850 NanoTech

Servos HXT500

It doesn’t seem very critical to me if the battery is mounted on the top or bottom.  If on bottom, the Velcro strap and foam block prevent grinding it into the pavement on landing. 

A cautionary tale

I was flying the mega at the field, doing horizontal figure 8s and all of a sudden the motor/prop noise just stopped.  It was going sorta fast, so I had plenty of momentum, allowing a glide back to the runway.  As it got closer I could see something hanging down from the back of the wing.  The motor mount had come unglued from the wing and collapsed, but all the pieces were there, so luckily the CG didn’t change and I retained control.  So, if you build one, make sure to reglue the motor mount.  Below is a pic of the prop damage.  I lost the prop and O ring, but nothing was broken and all the parts were there.  So, I just re glued the interlocking motor mount together and to the wing using foam tack.

Wing Damage from Motor Mount Issue

I did buy a bare wing and will put together another Mega with some digital servos.  The HXT500s don’t seem to center very well, I have to retrim almost every flight.

So, if you’re looking for something a little different with a bit of punch, you might give a Mega Poppy a try. 

Happy flying
